The ancient well is located on the south side of the street of the 90% Palace Palace. It is close to the main complex of the palace. It is an important drinking well in the palace. The well is round and engraved with beautiful octagonal sunflowers. One is beautiful and the other is non-slip. The inner and outer edges are carved with round bevels, and the entire well platform is built with light green hemp stone. The surface of the well platform is slightly spherical, and the inside is high and the outside is low, preventing turbid water from flowing back to ensure drinking water hygiene.
